Backflow Tester Refresher Courses:
The VC Environmental Health Division (VCEHD) has made revisions to the Backflow Assembly Testing Program in accordance with the adoption of the State Water Resources Control Board’s (SWRCB) Cross-Connection Control Policy Handbook (CCCPH). Due to these changes, the VCEHD will no longer offer or require refresher courses from testers looking to re-register with this Division.
Registered applicants are responsible for maintaining the continuous validity of all necessary licenses and certificates. Failure to keep these credentials current may lead to the invalidation of their VCEHD backflow assembly tester registration.
